1. A method of reproducing three-dimensional images of an object illuminated by or emitting any of the types of radiation known as x-rays, ultraviolet, visible light, infared, microwaves, particle radiation, inluding the steps of:
- exposing a radiation blocking element to said radiation;
establishing a pinhole window in said element through which the radiation is restrictively transmitted onto an imaging surface in a non-focused manner to form a complete image having an intensity pattern dependent on window position;
imparting scanning movement to said window to produce a series of complete images of said object on the imaging surface of different intensity patterns;
converting the image-forming radiation impinging on the imaging surface into signal energy;
converting said signal energy into a transparent image on a viewing screen that is locally variable in transmissivity;
emitting radiation from a movable emission location on a display surface spaced behind said viewing screen;
directing said radiation from said movable emission location to said viewing screen; and
imparting movement to the emission location on said display surface in synchronism with said predetermined scanning movement of the window in said radiation blocking element to reproduce an image of said object on said viewing screen that is observed with parallax.

Abstract
Reflected illuminating radiation is transmitted through a restricted window in an opaque surface undergoing scanning movement to project an image pattern on a closely spaced imaging surface from which the image pattern is reproduced on a viewing screen. The viewing screen is locally variable in transparency to provide images of objects viewed by observers with parallax.

9. A method of reproducing images of an object illuminated by or emitting any of the types of radiation known as x-rays, ultraviolet, visible light, infared, microwaves, particle radiation, for three-dimensional perception purposes, including the steps of:
-
exposing a radiation blocking element to said radiation; establishing a pinhole window in said element through which the radiation is restrictively transmitted image-wise onto an imaging surface in a non-focused manner with an intensity pattern dependent on the location of the window; imparting a predetermined scanning movement to said pinhole window to produce a series of complete images on the imaging surface with different intensity patterns; converting the image-forming radiation impinging on the imaging surface into signal energy; converting said signal energy into an image on a display surface; and directing radiation from said image on the display surface through a second window in an image blocking element, said second window undergoing scanning movement in synchronism with said pinhole window.

10. For use with a camera detecting illumination by or emitting any of the types of radiation known as x-rays, ultraviolet, visible light, infared, microwaves, particle radiation, reflected from an object for three dimensional image perception of said object in response to a scanning operation, a device for imparting a three dimensional character to the image produced by the camera including a radiation blocking element spaced in front of the camera having a pinhole window through which the radiation enters the camera with an intensity that is a function of the angle of incidence at an instantaneous location of the window, an imaging surface onto which the radiation transmitted through said window in a non-focused manner is received to form a complete image of the object, said imaging surface being located in parallel spaced relation to said element, means for changing the location of said window in accordance with the scanning operation of the camera to vary the intensity pattern of the radiation forming said complete image as a function of the window location, a receiver operatively connected to the camera having a display surface from which radiation is emitted at a location corresponding to said location of said window, and a viewing screen spaced from said display surface to receive said radiation emitted therefrom, said viewing screen having a locally variable transmissivity.
